Description

The MPX4115A series is designed to sense absolute air pressure in altimeter or barometer (BAP) applications. Freescale's BAP sensor integrates on-chip, bipolar op amp circuitry and thin film resistor networks to provide a high level analog output signal and temperature compensation.

Wiring

Example Code

The output voltage is a linear function of the pressure and does not need any compensation for errors within the 0° - 85° C temperature range. The error correction outside this range is given in the data sheet.
